Safety Guide

Be sure to check the entire system for any shipping damage or parts loss. Also note damage to the shipping

cartons. Contact US Water Systems at 1-800-608-8792 to report any shipping damage within 24 hours of de-

livery. Claims made after 24 hours may not be honored.

Small parts, needed to install the system, are in a parts bags. To avoid loss of the small parts, keep them in the

parts bag until you are ready to use them.

Unpacking / Inspection

 Check and comply with your provincial / state and

local codes. You must follow these guidelines.

 Use care when handling the water treatment sys-

tem. Do not turn upside down, drop, drag or set on

sharp protrusions.

 The carbon Superfilter system works on 12 volt-60

Hz electrical power only. Be sure to use only the

included transformer.

 Transformer must be plugged into an indoor 120

volt, grounded outlet only.

 WARNING: This system is equipped with a UV

light to remove biological contaminants. Although

this treatment system is in place, US Water Sys-

tems recommends that bacteria levels be checked

periodically to ensure the UV light system is operat-

ing properly. Coliform and E.coli most importantly.

Proper Installation

This water treatment system must be properly installed and located in accordance with the

Installation Instructions before it is used or the warranty will be void.

 Do not install or store where it will be

exposed to temperatures below freezing or

exposed to any type of weather. Water

freezing in the system will break it. Do not

attempt to treat water over 100°F.

 Do not install in direct sunlight. Exces-

sive sun or heat may cause distortion or

other damage to non-metallic parts.

 Properly ground to conform with all govern-

ing codes and ordinances.

 Use only lead-free solder and flux for all

sweat-solder connections, as required by

state and federal codes.

 Maximum allowable inlet water pressure is

125 psi. If daytime pressure is over 80 psi,

night time pressure may exceed the maxi-

mum. Use a pressure reducing valve to re-

duce the pressure.

 WARNING: Discard all unused parts and

packaging material after installation. Small

parts remaining after the installation could

be a choke hazard.

The Fusion Superfilter Oxi-Gen system provides iron, sulfur and manganese removal

throughout the home. The Fusion Superfilter Oxi-Gen system should be installed at the point of

entry to treat your entire home, both hot and cold water.

The Fusion Superfilter Oxi-Gen system’s backwashing tank removes iron, sulfur and

manganese using oxidation. When water is used in the home, hydrogen peroxide is injected in

the Fusion Superfilter Oxi-Gen feed to create super oxidation during operation. The Catalytic

Carbon media in the Fusion Carbon Superfilter system tank provides filtration when the system

is in service to collect contaminants oxidized by the hydrogen peroxide. These contaminants

are backwashed from the media surface when the system regenerates.

Fusion Superfilter Benefits

 Iron, Manganese & Sulfur Removal

 Virtually maintenance free.

 Improves the efficiency of water-using appliances

 Simple installation

 Safe for landscaping and lawn watering.

 Compatible with all on-site and community wastewater treatment systems

The GreenWave Ultra system provides protection from scale formation throughout the home.

The GreenWave system should be installed after the Fusion Oxi-Gen system to treat your

entire home, both hot and cold water, or it can be located directly before a water heater or

other device (e.g. sauna, etc) that requires protection from hard water.

The GreenWave Ultra reduces or eliminates scale formation on internal and external plumbing

surfaces as well as reducing spotting and streaking normally associated with hard water.

The GreenWave Ultra prevents scale by transforming the normal dissolved hardness minerals

into undissolved crystal micro-particles. These crystals stay suspended in the water and

dramatically reduce the scaling potential of hardness minerals. Therefore the problem of

internal build¬up of scale in pipes, water heaters and on fixtures and glass is greatly reduced.

The GreenWave Ultra is not a water softener – Low or phosphate-free cleaning products are

recommended to achieve optimum results. Modern surfactant or detergent based, liquid soaps

are preferred over old-fashioned fashioned caustic solid soaps.

Unlike softened water, the GreenWave Ultra treated water maintains the beneficial essential

mineral content of your water and is safe to drink.

GreenWave Tank Benefits

 Chemical Free Scale Prevention. Cost savings and environmental benefits

 Virtually Maintenance Free. No salt bags or other chemicals to buy, transport and store

 Beneficial minerals retained for more healthful drinking water

 Improves the efficiency of water-using appliances

 Simple installation – no electrical and drain hookup

 Safe for landscaping and lawn watering. No need for costly plumbing bypasses

 Compatible with all on-site and community wastewater treatment systems

 Not subject to water softener restrictions and "bans"

US Water UV Light Introduction

This point-of-use system allows for simple installation and operation due to its high output

lamp and compact reactor. The reactor is an axial flow design with superior hydraulics, com-

pact design and 1” NPT connections. The controller is a simple plug in device connecting to

the lamp with a safety cap.

Water Quality Guidelines

Iron < 0.3 ppm (0.3 mg/L)

Hardness < 7 gpg (120 mg/L)

Turbidity < 1 NTU

Manganese < 0.05 ppm (0.05 mg/L)

Tannins < 0.1 ppm (0.1 mg/L)

UV Transmittance > 85%

The UV light system uses ultraviolet let to kill bacteria and other organics in the water source.

The light from the UV bulb passes through the water and destroys the organic contaminants.

The UV bulb is utilizes a quartz sleeve on the outer portion to isolate the water from the UV

bulb element.

WARNING!

If this quartz sleeve becomes coated or stained it will reduce the light that can pass

through the water in the chamber, thus inhibiting the bacteria removal by the UV light.

It is crucial that the iron, manganese and any tannins in the water are removed prior to

the UV to ensure the light is penetrating the quartz sleeve and its’ full intensity.

Operation

The US Water Systems UV comes with a feature laden controller that incorporates both the lamp driver

(ballast) and control features in one water-tight case. CAUTION: Prior to performing any

maintenance on your UV system, you must always disconnect the power.

USWATER 5.0 & USWATER 6.0 Controller

This controller features a power factor corrected, constant current lamp

driver with a universal power input. A full color LCD screen provides

the user with a detailed description of the system's performance in

addition to providing any applicable fault messages and system

diagnostics. The controllers used in both the USWATER5.0 and USWATER6.0

are identical. The difference is that the USWATER 6.0 series of products

includes a UV intensity monitor. All USWATER 5.0 and USWATER 6.0 controllers

include an "infinite expandability port" located on the right side of the

controller. Simply plug in an optional UV sensor module into the

expandability port of a USWATER 5.0 controller and the system will now

monitor the UV intensity of the system!

US Water UV Light Introduction

USWATER 5.0 & USWATER 6.0 Power-up Sequence

Upon start up, the 5.0 & 6.0 controller will run through a diagnostic start-up and the sequence will

be displayed as follows on the color LCD:

Next, the controller checks for the installation of any optional modules that may be installed on the

system. It first checks to see if a module is installed and then either initializes the module to

function with the controller or returns a "not detected" screen and moves on to the next module.

The screens will appear as follows:

UV Sensor

Module Check

Solenoid

Module Check

4-20 mA

Remote Alarm

Module Check

Once the controller has finished checking for the installation of all available modules a single screen is dis-

played showing which specific modules are installed and activated on this particular system. Please Note:

If the corresponding module icon is not displayed on this screen, then that module is not installed on this

system. If you believe this module is installed correctly, recheck the applicable connections to ensure a

solid connection point and then restart the controller. The controller then continues to optimize the lamp

efficiency by waiting 60 seconds to allow the lamp to reach its optimum output. Finally, a final "start-up

complete" screen is displayed. These screens will appear as follows:

USWATER 5.0 Operational Screens

On USWATER5.0 systems (without the UV monitor), the default screen shows the US Water Systems Home

Screen. At an y point du r ing o per at i o n t h e user i s ab l e to s croll throug h the US Water Systems

Home Screen, Lamp life remaining and QR Code/Contact Info screens by simply pressing the button

located on the front of the controller.

US Water UV Light Introduction

USWATER 6.0 Operational Screens

On systems that have the UV module installed (and on all USWATER6.0 systems), the default screen

shows the % UV Intensity. At any point during operation the user is able to scroll through the % UV

Intensity, Lamp life remaining an d QR Code screen s b y s i m pl y p r es sin g t he bu t t on lo c at ed

on the

front of the controller.

USWATER 6.0 % UV Intensity

If your system is equipped with a UV sensor the % UV Output screens will indicate the level of UV intensity

that is being detected within the reactor by the sensor. This will always be visible on the Home Screen of

the controller. Things that can affect the % UV Output are poor water quality, scaling of the quartz

sleeve and/or sensor, lamp failure, expired lamp life and sensor failure. The following screens show the

% UV Output dropping on a monitored system.

US Water UV Light Introduction

Once the UV output drops below 56%, the numbers and warning sign switch to red and a 15 second intermit-

tent audible chirp is given off by the ballast. When the output drops below 51%, the display switches to a

solid red and a constant audible signal is provided. The screens alternate between this solid red

screen and another screen indicating "water may be unsafe for consumption". At this point, the controller

also provides a signal to de-activate the solenoid valve, shutting off the flow of water if a solenoid valve is

installed on the system.

USWATER5.0 & USWATER6.0 Lamp Countdown Sequence

The USWATER5.0 & USWATER6.0 counts down the number of days until a lamp change is required. The

operation is as follows:

Once the lamp has seven days remaining until a lamp change is required, the screen changes to a yellow

caution screen. At this point, an audible chirp is given off by the ballast to draw your attention to the

pending lamp change condition. When the controller passes the zero day threshold, the screen chang-

es to solid red and cycles between a red "lamp expired" screen and a "water may be unsafe for consump-

tion" screen. The same intermittent audible chirp is heard throughout this lamp expired sequence.

At any point during this sequence, the audible chirp can be deferred by holding the controller button

down for a period of five seconds. The screen shown below will appear for five seconds indicating that

the audible deferral has been activated and then the system switches back to the cur-

rent lamp change or lamp expired screen. This audible deferral will last for seven

days after which then the alarm will sound once again. This audible deferral feature can

be activated as many times as you wish. PLEASE NOTE: During the condition of lamp

expiration and audible deferral, the water may be unsafe for consumption and should

not be consumed without another form of disinfection.

US Water UV Light Introduction

USWATER5.0 & USWATER6.0 Lamp Countdown Reset Sequence

After changing the lamp on the USWATER5.0 & USWATER.0 systems, the controller must be reset in

order for the system to begin its countdown function on the newly installed lamp. To perform this

reset, you must firmly depress the button on the front of the controller and then manually plug the

power cord back into the wall outlet initiating power to the unit. Keep holding down the button for five sec-

onds until you hear an audible chirp indicating the controller has reset the internal timer.

Release the switch and the lamp countdown feature has now been reset. The following two screens will be

displayed during this process.

USWATER5.0 & USWATER6.0 Failure Modes

The US Water Systems controller continuously monitors your UV system and if there is a problem with the

system the controller will provide both a visual and audible signal indicating the specific fault that may be

adversely affecting the operation of your system. The fault conditions are listed in a priority sequence as

follows:

LAMP FAILURE: If at any tim e duri ng the operatio n o f the

system, the UV lamp fails to be illuminated, the controller will

return both an audible and visual signal indicating lamp failure. In

addition, a constant audible buzzer will sound during lamp failure.

UV SENSOR FAILURE: Assuming the system has a UV Sensor

installed, if at any time during the operation of the system, a UV

sensor fails, the controller will return both an audible and visual

signal indicating sensor failure. For sensor failure, the controller

will cycle between "sensor failure" and "water may be unsafe for con-

sumption" screens as an added precaution. In addition, a con-

stant audible buzzer will sound during sensor failure.

US Water UV Light Introduction

SOLENOID MODULE FAILURE: Assuming the system has an op t io n al So le-

noid Module installed, if at any time during the operation of the system, a

solenoid valve fails to operate, the controller will return both an audible and

visual signal indicating solenoid failure. In addition, an intermittent (15 sec)

audible buzzer will sound during solenoid failure.

4-20 mA MODULE FAILURE: Assuming the system has an opt io n al 4-20 mA

Module installed, if at any time during the operation of the system, a 4-20

mA module fails, the controller will return both an audible and visual signal

indicating a 4-20 mA failure. In addition, an intermittent (15 sec) audible

buzzer will sound during a 4-20 mA failure.

REMOTE ALARM MODULE FAILURE: Assuming the system has an op-

tional Remote Alarm Module installed, if at any time during the operation of

the system, a remote alarm module fails, the controller will return both an

audible and visual signal indicating remote alarm failure. In addition, an in-

termittent (15 sec) audible buzzer will sound during remote alarm failure.

ETHERNET MODULE FAILURE: Assuming the system has an optional Ethernet

Alarm Module installed, if at any time during the operation of the system, an

Ethernet module fails, the controller will return both an audible and visual

signal indicating Ethernet failure. In addition, an intermittent (15 sec) audi-

ble buzzer will sound during Ethernet failure.

USWATER 5.0 & USWATER 6.0 QR Codes

A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional

code) first designed for the automotive industry. US Water Systems uses the QR code to store a link to a

specific page on our website. Users with a camera phone equipped with the correct reader application

can scan the image of the QR code and over a wireless network connect to a US Water Systems web page

in the phone's browser. US Water Systems' QR webpage has information on how to purchase replacement

components as well as a helpful video directory on system servicing

(i.e. How to change a UV lamp or quartz sleeve). To access the QR code on the USWATER5.0 or

USWATER6.0 controller simply press the control button twice and the QR code screen will appear as

follows:

US Water has pioneered the use of hydrogen peroxide in water treatment for the eradication of

iron (rust), sulfur (hydrogen sulfide odor) and manganese for nearly 20 years. It can truly be

called an "Eradication System" because it TOTALLY removes iron, sulfur and manganese.

Properly sized, an Fusion Superfilter Oxi-Gen Hydrogen Peroxide System from US WATER is

THE MOST EFFECTIVE METHOD for removing iron, rust, sulfur, manganese and hydrogen

sulfide (the rotten-egg odor) from your water supply. The Fusion Superfilter Oxi-Gen system

uses Catalytic Carbon media in the backwashing filter to collect the contaminants removed by

the hydrogen peroxide. Hydrogen Peroxide is not a hazardous chemical - to the contrary,

hydrogen peroxide (H2O2) is composed of the elements of water: Hydrogen and Oxygen.

There is nothing foreign or chemically added to the water supply. Unlike chlorine, hydrogen

peroxide requires no contact time and the reaction (oxidation of iron, rust, sulfur, manganese

and hydrogen sulfide) is immediate. The Fusion Superfilter Oxi-Gen Hydrogen Peroxide

System is the answer to practically any iron, rust, sulfur, hydrogen sulfide or manganese

problem, and is backed with our 90-Day 100% Satisfaction Guarantee. US Water Systems

guarantees 100% iron, manganese and sulfur removal with its Fusion Superfilter Oxi-Gen

System which utilizes Hydrogen Peroxide or H2O2.

Hydrogen peroxide or H2O2 is a powerful, yet

versatile oxidant that is both safe and effective.

Consider the H2O2 advantages and you’ll know

why this is the ONLY sure way to eradicate iron,

manganese and sulfur.

Powerful - H2O2 is one of the most powerful

oxidizers known and is much stronger than chlorine, chlorine dioxide, and potassium

permanganate.

Safe - H2O2 is formed by the action of sunlight on water and is a natural purification system for

our environment. Consequently, H2O2 has none of the problems of gaseous release or

chemical byproducts that are associated with other chemical oxidants. And since H2O2 is

totally miscible with water, it reverts back to hydrogen and oxygen after the reaction is

complete.

Versatile - Hydrogen Peroxide is lethal to iron, sulfur and manganese. PERIOD!

Selective - In itself, H2O2 is a fantastic oxidizer, much better than chlorine and potassium

permanganate. It poses no health hazard and ERADICATES 100% OF THE IRON, SULFUR

OR MANGANESE – ALL THE TIME – GUARANTEED!

UV Light

The Fusion Superfilter Oxi-Gen iron, sulfur and manganese eradication system uses Hydrogen

Peroxide (H2O2) to oxidize contaminants in your water source. The chemical name for

hydrogen peroxide is H2O2. As you can see it is very similar to water (H2O) but with one

additional oxygen molecule. Hydrogen peroxide is injected into the water stream

proportionally. The water meter will engage the chemical injection pump based on the flow

rate of the feed source water and the settings on the pump control.

When water is being used the water meter sends a pulse to engage the pump. So when large

amounts of water are being used the pump will run more frequently during the usage period

than in times when a small amount of water is being used. The standard programming is set to

a 5 second control. At 100% the pump will stay engaged for 5 seconds. At 50% the pump will

stay engaged for 2.5 seconds. In some applications with high flow rates or high contaminant

levels, this setting may need to be changed if a residual H2O2 cannot be achieved. There are

internal settings that can be changed to adjust the output rate. The pump settings can be

changed to 10 seconds at 0-100% or 20 seconds at 0-100% if need be. 80% of the

applications will use the standard setting (5 seconds).

When hydrogen peroxide is injected into the water stream, it oxidizes the iron, sulfur and

manganese from solution. This reaction is immediate. When these contaminants are oxidized

with hydrogen peroxide (H2O2) the extra oxygen molecule oxidizes the contaminants and the

by product is H2O (water). This is much safer than using chlorine in that chlorine can cause

other problems in the water stream such as chloramines and trihalomethanes (THM’s).

Once the hydrogen peroxide has been injected in the water it passes through the backwashing

Catalytic Carbon filter. The backwashing Catalytic Carbon filter uses Catalytic Carbon media

to act as a “catalysis” to remove the oxidized contaminants. As the water passes through

Catalytic Carbon filter, the oxidized contaminants are removed from the water and collected on

the Catalytic Carbon media. Once the water has passed through the Catalytic Carbon filter,

the water is iron, sulfur and manganese free! Extreme levels of manganese may require a

water softener in addition to the Fusion Superfilter Oxi-Gen system to polish the remaining

manganese.

The Catalytic Carbon filter will need to be backwashed at a specified/determined frequency. In

some applications this can be extended to 4-5 days. The typical frequency is 1-3 days.

frequency that can be used when considering the feed water contaminant levels. The factory

default will be 3 days.

The Importance of Contaminant Removal Prior to the GreenWave Tank

Iron and Manganese

Just as with conventional water softening media, the GreenWave media needs to be protected

from excess levels of certain metals that can easily coat the active surface, reducing its

effectiveness over time. Public water supplies rarely, present a problem, but if the water supply is

from a private well confirm that the levels of iron (Fe) and manganese (Mn) are less than 0.3 mg/L

and 0.05 mg/L respectively. Copper should be less than 1.3 mg/L.

Copper

Copper usually originates from new copper plumbing upstream of the GreenWave Ultra system. If

this condition exists, we recommend waiting 3-4 weeks before placing the system in operation. This

will allow the copper surfaces to be fully flushed and develop a natural protective surface. To

further minimize any problem with excess copper the installers should be advised to avoid applying

excess flux on the inner surfaces of the pipe and to use a low-corrosivity water soluble flux listed

under the ASTM 8813 standard. Once the plumbing connections are complete, place the

GreenWave Ultra system in bypass prior to following the startup procedure and flush the plumbing

for at least 10 minutes.

Cautions!

 Do not let the system freeze. Damage to the tank and pre-filter may result.

 The system must be operated in a vertical position. Do not lay it down during operation. The

system may be placed in any position for shipping and installation but must be operated in the

vertical position.

 Place the system on a smooth, level surface. Because the system operates in an UP-Flow,

fluidized bed mode, having a level surface is more important than with a softener or media filter.

 A bypass valve should be installed on every system to facilitate installation and service

(supplied).

 Observe all local plumbing and building codes when installing the system.

Notes to the Installer

The GreenWave Ultra system differs from a conventional softener or media filter in a number of key

respects.

 The system is light and only partially filled with media. This is normal. The UP-flow operation of

the system requires a large area of freeboard in the tank to allow the bed to fully fluidize.

 The GreenWave tank has no under-bed so you can tip the system over without any fear of

upsetting the media. This makes transportation and installation much easier than conventional

systems. The carbon Superfilter does have under-bedding and should not be moved once

filled.

 Because the GreenWave Ultra system operates in the UP-Flow mode, the tank connections are

opposite of what a normal softener will use.

 Please see the "important note about iron, manganese and copper" above.

Installation, Operation and Maintenance Manual

385-GWU-1000, 385-GWU-1500, 385-GWU-2000

WATER PRESSURE: A minimum of 20 pounds of water pressure is required for re-

generation valve to operate effectively.

ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is

required. Note: Other voltages are available. Please make sure your voltage supply is

compatible with your unit before installation.

EXISTING PLUMBING: Condition of existing plumbing should be free from lime

and iron buildup. Piping that is built up heavily with lime and/or iron should be replaced.

LOCATION OF FUSION SUPERFILTER TANK AND DRAIN: The Fusion Superfilter

tank should be located close to a drain to prevent air breaks and back flow.

BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not

equipped with one. The Catalytic Carbon Superfilter is equipped with a bypass valve.

CAUTION: Water pressure is not to exceed 80 psi, water temperature is not to exceed

110°F (43°C), and the unit cannot be subjected to freezing conditions or direct sunlight.

1. Use a piece of duct tape to cover the top of the distributor tube in the tank. Be sure the

distributor tube is centered in the tank. The distributor tube should be flush with the top

of the tank or no more than 1/4” below flush. Install the supplied funnel and pour the

gravel in the tank first. Each system will ship with gravel and Catalytic Carbon media.

Pour the gravel in the tank first then pour in all the Catalytic Carbon media that was

shipped in the tank last. US Water does not ship “extra” media. If possible, fill the car-

bon tank with water and allow it to soak while the other components are installed. This

will reduce the backwash/ rinse time needed to flush out the carbon fines during the

startup procedure.

2. Lubricate the distributor O-ring and the tank O-ring. Then install the upper basket (may

look different than the pictures below) on the bottom of the valve by lining up the tabs then

turning the basket clockwise to lock it in place. Place the upper basket over the distributor

tube and push the valve on the tank. Thread the valve on the tank by turning it clockwise.

Be sure not to cross-thread the valve on the tank. Tighten the valve hand tight, then snug it

further by tapping it with the palm of the hand. DO NOT use tools to tighten the valve or

damage could occur. Move the carbon unit to the side and start the injection panel installa-

tion
